Why does pfs_mount fail with the message 'Not Owner' when
I try to use it?
This is a common problem. You (root) are probably in more than 8 groups.
Run groups(1) to check.
There are two work-arounds to the problem:
+ Apply the latest PFS patch:
o 10.20: PHCO_15453
o 11.00: PHCO_16438
+ Temporarily remove root from enough groups to bring it under the limit:
o Backup /etc/group.
o Edit /etc/group so that root is in 8 or fewer groups.
o After running pfs_mount, restore the original version of /etc/group.
